I HIIIHIHHH Patented Oct. 23, 1934 1 UNITED STATES PATENT .OFFI-CE LEATHER "ROUGHING moor. Henry Jensen, Canton Center Conn. Application February 16, 1934, Serial o. 711,561 I Claims. (01. es zo i may have a strong adherence.

1 This invention relates to a tool which is designed to. be used. for roughing the surfaces of leather preparatory to cementing the surfaces together, in order that the cementing material The tool is particularly adapted for roughing the laps of leather belts which are to be cemented together and also for roughing the surfaces of shoe soles which are to be cemented to the bottoms of shoe uppers, but

1 its use is not limited to belt manufacturers and shoe makers.

The object of the invention is to provide a tool for the purpose mentioned which will be efiicient for a longtime, which can be quickly cleaned i when the roughing element becomes clogged with abraded fibers and dust, and which can be easily and cheaply renewed when the abrading element becomes impotent. In attaining this object the tool comprises a cylindrical wire-bristle brush 5 mounted in a yoke that is attached to a handle. The brush when used is held from rotary movement but when a section becomes clogged it can be loosened and turned so as to present a cleared section. A comb is adjustably clamped to the yoke with itsteeth projecting between the bristles of the brush and when the brush is loosened, by rotating it the comb teeth will automatically clean all fibers and dust from the bristles. When the brush becomes so worn that it is no longer effii cient it may be readily dismounted and a fresh brush substituted or a new strip of carding material fastened around the cylindrical body of the brush.

In the accompanying drawing Fig. 1 is a section through the handle, the brush mounting means and the cleaning comb.

Fig. 2 is a vertical section of the brush and its mounting means.

Fig. 3 is a perspective view of the cleaning comb.

In the embodiment of the invention illustrated the brush comprises a cylindrical section 1 desirably of wood, although it may be made of other material, with a softer padding 2 on its periphery and wire bristles 3 projecting from the padding. The bristles are preferably bent in one direction so that they will form sharp abrading teeth that when drawn over the surface to be roughened will scratch and raise the fibers.

This brush is mounted on a bolt 4 which passes through the center of the brush and perforations in the limbs of a yoke 5. One end of the bolt has a head 6 that is engaged by an outturned end 7 of the yoke in such manner that the bolt cannot .turn.v At the other end the bolt is threaded and provided with a thumb clamp nut 8 which when screwed up holdsthe brush from turning in the yoke, but which when loosened allows the brush tobe freely rotated. Upon removal of the nut and bolt the brush may be detached. 6:

The closed end 9 of the yoke has a perforation which fits the shank 10 near the head 11 of a bolt 12 that extends longitudinally through the handle and on the other end has a nut 13 that is sunk in the end of the handle.

The'body of the cleaning comb 14 is slotted and its two limbs extend between the under face of the bolt head 11 and the inner face of the yoke. The outer end of the comb body is bent upwardly and provided with teeth 15 that normally project 701 between the bristles of the brush. By giving the handle a slight turn the bolt head may be loosened so that the comb may be adjusted in or out to the needed degree, or may be entirely removed if so desired.

When the tool is to be used the thumb nut is screwed up so as to hold the brush from rotating and the handle grasped and the brush drawn across the surface to be roughened. When the bristles of the exposed section that are utilized 80. for roughening become filled with fibers and dust so that they are inefiicient, the thumb nut is loosened and the brush rotated to a degree which affords a clean section of bristles. The clamp nut is then tightened and the brush is again in condition for eificient use. After the entire surface of the brush becomes clogged with fibers and dust, or if desired before it becomes completely clogged, the thumb nut may be loosened and the brush rotated so that the comb will clear the bristles.

This tool is handy forbelt makers, shoe makers and the like artisans. It is always ready for use and after use can be quickly cleaned. It is inexpensive to manufacture and can be used by any one. The outturned end 7 of the yoke 5 fits against the head 6 of the brush supporting bolt 4 so that bolt is held from rotation when the thumb nut is tightened or loosened. As the comb body is held beneath the head of the bolt which attaches the yoke to the handle, a simple turn of the handle with relation to the yoke releases the comb so that it may be adjusted or removed. The shank immediately underneath the head of the handle bolt, is squared so as to fit the slot in the comb body and this so holds the bolt that when the handle is turned the nut in its lower end causes the handle to tighten or loosen.

The invention claimed is:

1. A leather roughing tool comprising a cylindrical brush rotatably mounted between the limbs of a yoke, a bolt passing through the yoke and brush and having a head at one end held from turning by a portion of the yoke, and a thumb nut on the other end which when tightened clamps the brush from rotation but when loosened allows the brush to be rotated, a handle attached to the yoke, and a comb clamped to the yoke and provided with teeth adapted to project between the brush bristles.

2. A leather roughingv tool Comprising a cylindrical brush mounted between the limbs of a yoke, means for clamping the brush from rotation, a handle attached to the yoke by a bolt, and a comb with teeth adapted to project between the brush bristles adjustably clamped between the yoke and the head of said bolt. v

3. A leather roughing tool comprising a cylindrical brush rotatably mounted between the limbs of a yoke, a bolt passing through the'yoke and brush and having a head at one end held from turning by a portion of the yoke, and a thumb nut on the other end which when tightened clamps the brush from rotation but when loosened allows the brush to be rotated, a handle attached to the yoke by a bolt, and a comb with teeth adapted to project between the brush bristles adjustably clamped to the yoke.

4. A leather roughing tool comprising a cylindrical brush rotatably mounted between the limbs of a yoke, means for clamping the brush from rotation, a handle fastened to the yoke by a bolt, and a comb with teeth adapted to project between the brush bristles, the body of said comb having a slotted end that is clamped between the yoke and the head of said bolt.

5. A leather roughing tool comprising a cylindrical brush mounted between the limbs of a yoke, a bolt passing through the yoke and brush, a thumb nut on the bolt which when tightened clamps the brush from rotation but when loosened allows the brush to be rotated, a rotatable handle associated with the yoke, a comb with teeth adapted to project between the brush bristles, and means for securing the comb to the yoke, said means being tightened or loosened by turns of the handle relative to the yoke.
